Several others

Croses, Piel, Gull, Mauboussin, ...

There are other tandems, of course. Several are very close to
the configuration of the designs of Henri Mignet. I just mention a
few.

Like you can see, the Pou hasn't lost his followers. And you
will be convinced that there will be a new revival of the Pou in
the USA, when reading the stuff on http://www.flyingflea.com.ar/home . In France,
the revival began a lot earlier. But that will be not hard to
understand when you see the several French designs you can find. We
(Dutch spoken people in Belgium) have a saying "Geen sant in eigen
land", which means "No saint in own country". I am sure that many
designers or whatever have become victim of this saying. Mignet
sure wasn't. The Mignet firm was very active in France.

There are several other designs with tandem configuration. I
found a few in the ultralight aviation. One of them is the Sunny.
It is a boxed wing tandem ultralight. Due to the fact it is a boxed
wing it is a very rigid aircraft. Here you can see the prototype.
Later it got a open fuselage. I got in contact with the
designer of the Sunny, Dieter Schulz. Together we assembled enough
info to make some extra pages about this airplane.

I found this info on the net about this tandem. Source:

"The famous "Flying Flea" isn't the only successful light plane
nowadays with tandem tendencies. M. Pierre Mauboussin has turned
out a big-tailed job of more conventional design than the "Flea"
which is attracting much favorable comment among French sporting
pilots. The performance of this little ship is not to be sneezed
at. Powered with a 40 hp. Train engine, the Mauboussin Hemiptere
steps along at a top speed of 99.4 m.p.h., cruises at 84 m.p.h.,
and lands at the very low speed of 28 m.p.h. Cruising range is 335
miles, so that the owner of the "Hemiptere" can do a little more
than puddle jump around airports. Service ceiling is 12,464
feet."

Another ultralight is the Gull. The only data I have personally
on this one is a small, unclear picture and the fact that it was
distributed by Eartstar Aircraft Inc. I read "Both the Ultra Gull
Deluxe and the Laughing Gull come equipped with three-axis
controls, main wheel brakes, double surfaced wings, shock-absorbing
landing gear, 4130 Chromoly steel/enclosed fuselage and steerable
nosewheel. Earthstar Aircraft Inc., Star Route Box 313, Santa
Margarita, Calif. 93453 (805) 438-5235" (quote from "Homebuilt
aircraft", febr. 1986). You can see that the wings have the same
span (well, that is what I think to see on the picture). The
connection between both wings should enhance the rigidity of the
design. But I have no clue about its stability.
Can anybody tell me more about this one?

I got this info from Christophe Meunier:"Type : Earthstar
UltraGull U1 Data Source : Jane's All the World Aircraft 1988-89
p568-569, 1986-87 p569, 1985-86 p685 (+ 1990-91 page not recorded).
American aircraft, lightweight, that can be trailed behind a car
without wing removal. Very small, due to high lift of the dual
wing.Take off and landing in less than 40 meters (STOL). Version
U1, and U1H with better performances (shorter span, bigger engine),
for amateur construction. Version Deluxe with better engine
covering and booms directed more below. Single seat. 1 engine of 30
to 60hp Span 7.3 to 6.1 meters Length 3.2 meters Weight 0.1 ton
empty - 0.23t maximum Maximum speed 240km/h."

Recently I got permission from vula.org (Vintage Ultralight &
Lightplane Association) to use two pictures I found of this
project. The other pictures came from a visitor, sadly i forgot his
name. Sorry :(
